Signs of a dog losing vision can be quite obvious. Your dog might bump into walls or furniture or have trouble locating their dog food or favorite dog toys. Your dog might stop making eye contact with you. The signs can also be subtler, such as being reluctant to jump on or off the couch, a new level of dog anxiety, or becoming clingy.

Subtle clues that your four-legged pal’s vision is failing include: Clumsiness Engaging in play less often Refusal to go outside Excessive sleeping You can also check your dog’s eyes for physical signs like blue-tinted or cloudy eyeballs and enlarged pupils. Schedule a veterinary exam immediately if you’re worried that your dog is going blind.

In most cases, blindness develops gradually in dogs, and there are markers to help you tell. Watch your dog's eyes: You might see cloudiness, or white spots in their eyes. They're having trouble navigating: Is your dog bumping into objects or walls? Do they not respond to movement?
